A digital image processing apparatus analyzes an image from a camera to display color information. It includes a digital signal processing unit that detects digital color signals in the image and calculates a color distribution chart showing the proportion of each color. The processing unit uses a memory storing a color information table to find color information for each digital color signal. It also calculates an "optimized color arrangement distribution chart" based on a color distribution information table of pre-defined, desirable images ranked by criteria like similarity, familiarity, and contrast. Finally, a display unit overlays the calculated color distribution chart and the optimized chart on the original image.

The digital image processing apparatus, as described previously where it analyzes an image from a camera and displays color information by detecting color signals, calculating color distributions, and overlaying optimized color arrangements, calculates the color distribution chart based on individual pixel colors, providing a fine-grained color analysis of the image. Thus, each pixel's color contributes to the overall color distribution chart.
3. The apparatus of claim 1 , wherein the digital signal processing unit changes the colors of the entire image into the optimized color distribution chart by user determination, the user determination being made after the display of the optimized color distribution chart.
The digital image processing apparatus described earlier, which analyzes images and overlays optimized color distributions, allows a user to change the colors of the entire image to match the optimized color distribution chart. After the optimized color distribution chart is displayed, the user can decide to apply the optimized colors to the original image.

A digital image processing apparatus captures an image from a camera and converts it into digital color signals. It then references a color information table in memory to obtain color information for these signals. A color distribution chart, representing the statistical distribution of colors in the image, is calculated. The system also accesses a color distribution information table (containing color distributions from desirable images rated by similarity, familiarity, etc.) to obtain optimized color arrangements for those colors. Finally, it identifies the optimized color arrangement closest to the calculated color distribution chart and adjusts the image colors accordingly.

The apparatus of claim 4 , wherein the digital signal processing unit comprises: the memory; a search portion for obtaining the color information corresponding to the digital color signals of the image from the color information table stored in the memory and obtaining the optimized color arrangement information corresponding to the digital color signals of the image from the color distribution information table stored in the memory; a color distribution chart calculation portion for calculating the color distribution chart of a main color signal and sub-color signals of the image based on the obtained color information and calculating the optimized color distribution chart of the main color signal and the sub-color signals of the image based on the obtained optimized color information; and a color change unit for changing the colors of the image into optimized colors in response to a selection signal.
This digital image processing apparatus builds upon the previous description, which captures an image, converts it to digital color signals, calculates color distributions using color information and optimized arrangements from memory. It uses a memory, a search portion that retrieves color information and optimized arrangement information from color information and color distribution information tables, a color distribution chart calculation portion that computes the distribution charts for both main and sub-colors based on the color and optimized arrangement information.
